Hello.
I'm not sure if this is old news, but the last few days I have bin upgrading and fresh installing my friends and family laptops and PC's with Windows 10 via my USB stick and some asked about the serial key so I had a look around.
This little program I found gives you the serial key plus tells you the OEM key you have from ur previous OS.
